Diversion colitis is thought to result from nutritional deficiencies secondary to fecal diversion. Symptoms include hemorrhagic purulent rectal discharge, abdominal pain, and tenesmus. 5-Aminosalicylic acid (5-ASA) and N-butyrate enemas have been reported to help this condition non-spinal cord injury (SCI) patients. We report the case of a 49-year-old C6 ASIA B tetraplegic man who had received colostomy because of intractable ileus 10 years earlier. He presented with a 2-week history of rectal pain and bleeding. Abdominal and rectal examination on admission were unremarkable. Colonoscopy showed a partial stricture 70cm proximally to the rectum. The colonic mucosa appeared granular and friable with evidence of linear ulceration. Histopathologic study was consistent with colitis. The patient developed fever, abdominal distention, and extensive retroperitoneal air after endoscopy, suggesting colonic perforation. He was treated with daily 5-ASA suppository and total parenteral nutrition for the presumed diagnosis of diversion colitis, and intravenous antibiotics for perforated colon. After 6 weeks of treatment with 5-ASA, the patient had decreased rectal pain and bleeding. This experience suggests that diversion colitis may be a cause of abdominal discomfort in SCI patients and that 5-ASA may be used in the management of diversion colitis.     

Some fundamentals of B. F. Skinner's behaviorism.

Despite B. F. Skinner's prominence, his impressive written corpus, and the many authoritative presentations by others of his approach to psychology, the fundamentals of Skinner's psychology have never been addressed in any comprehensive manner. In this article, the authors take steps to fill this gap by synopsizing Skinner's written corpus into 12 fundamental points that seem to characterize his behaviorism.

Educators' perceptions of the D.A.R.E. program

This study examines the perceptions of educators about the Drug Abuse Resistance Education (D.A.R.E.) program, based on the results of a statewide survey among 286 fifth and sixth grade teachers and principals. Educators gave their highest ratings to teacher/officer interaction, the role playing exercises, and the graduation ceremony. Ratings of overall program quality and the impact of the program on students were both high. Block regression analysis was used to examine factors predictive of educators' views of D.A.R.E. D.A.R.E. program elements were the most important factors explaining variance in educators' ratings of over-all program quality and program impact on students. Altogether, 54 percent and 38 percent of the variance in both dependent variables were explained. The results are discussed in terms of the important role teachers and principals play as stakeholders in prevention education.     

E. G. B.: The early years and change of course.

Discusses why E. G. Boring left the laboratory to become the foremost historian of experimental psychology. The position of psychology in general and at Harvard in particular in the mid-1920s is examined, and it is concluded that Boring turned to history because he could not accept the current phenomenological or behavioristic approaches. The Zeitgeist had rendered Titchenerian structuralism obsolete so it was natural for Boring to devote himself to the history of the great sensory tradition. His inclusion of James and Freud among the "very great" psychologists showed his growth in appreciation of men outside the structuralist school. Boring's career exemplified the positive and negative interactions of eponyms with the Zeitgeist which he maintained was an essential factor in the progress of science. (19 ref.)

Study of the h.c.p.-f.c.c. phase transition in cobalt by acoustic measurements

Acoustic measurements have been performed in the vicinity of the h.c.p.-f.c.c. phase transition in cobalt. The main results are the following: At low frequency (~ 1 Hz), a high transitory internal friction peak is observed. It is shown that this internal friction is a function of T/vT temperature rate, v vibration frequency) but is not proportional to T/v. This behavior is explained in the framework of a recent model based on a Clausius-Clapeyron-like equation expressing the coupling between stress and phase transition; At medium (~5 KHz) and high (~ 20 MHz) frequencies, the transitory internal friction becomes negligible. However, a small peak appears accompanied by an elastic modulus decrease. It is shown that these anomalies are related to the shear modes parallel to the transformation plane. Thus, they might be related to the motion of the partial dislocations composing the h.c.p.-f.c.c. interface.
